The Application of the Concept of Extent of Reaction

Abstract
The concept of extent of reaction permits the definition of the related variable, degree of advancement. The expression of the concentrations in the reaction rate equation as a function of one degree of advancement variable leads to considerable simplification of the mathematical problem and yields a single differential equation to solve. However, the misuse of these concepts leads to wrong results, which have survived for 40 years even in textbooks on chemical kinetics. In fact, the definition of one degree of advancement variable for each elementary reaction step is required in the case of multistep reactions.
